she is almost 12 pounds now

my little guy was like this all the time until we bumped up his ounces he's going to be 7 weeks tomorrow and eats anywhere from 4-6 ounces at his feedings how much does she weigh? little man weighs almost 10 pounds so she could just need more formula or milk whichever you use but most doctors actually recommend you not give anything other than formula or breast milk until I believe it's three months.

i just found out my mom gives it to her n wen i get her home n just give her a 4oz bottle she still cry like she is still hungry

Even though I did with my oldest kid (20 yrs ago) I say no. Why are you considering it anyway if you don't mind me asking?

wat do i should i do she dont seem full n my mom has been doing dat wen i let her watch my child

No.
